Letters Patent No. 93,37 6, dated August 3, 1869.

IMPROVEMENT IN FIFTH-WHEELS FOR CARRIAG-ES.

The Schedule referred to in these Letters Patent and making part of thesame- To all-whom it may concern.-

Be it known that I, DANIEL WEA VER,-of Dayton, in the county ofMontgomery, and in the State of Ohio, have invented certain new anduseful Improve-' proved circle-iron or fifth-wheel, and

Figure 2 is a vertical section of the same, through the centre,lengthwise, of the axle.

Letters of like name and kind refer to like parts in each of thefigures;

The nature of my invention consists, principally, in the use of apivot-hub upon the lower side of the circle-iron, which fits into acorresponding socket in the lower plate, and relieves the king-bolt fromall lateral strain and. from all wear.

It further consists in the use of an arm, extending radially from thecentre of said circle-iron, and forming a part of the same, whichfurnishes a convenient and durable means for attaching the reach to saidcircle-iron, and thereby connecting the front and rear axles and It alsoconsists in forming said fifth-wheel and its connections in two parts,so as to permit of their being made of cast metal.

' In the annexed drawi ng-- I A represents the axle, having secured uponits upper side, by means of clips, a a, a bar or plate of metal, 13,which bar or plate has attached near its outer ends, and forming a partof the same, two segments of a circle, 0 O, the upper faces of which arehorizontal, and are elevated from one-half to three-quarters of an inchabove said bar.

A boss, I), rises from the centre of the bar B to a corresponding heightwith the upper surfaces of the segments G G, and is provided with around opening, from three-quarters to one inch in diameter, extending Drepresents the circle-iron or fifth-wheel, secured to and forming a partof a bar or plate, E, which corresponds in shape to the lower bar B, andis provided upon its lower side with a boss, (I, from which projectsdownward a hub, d, of suitable size and shape to fit loosely into theopening in the lower boss 12, forming I an axial-pivot for saidvcircle-iron. The upper side of the boss I) and the lower side oftheboss d furnish a suitable horizontal bearing for: said circle-iron,and

enable it, in'conuection with the segments 0 G, and corresponding ringI), upon the upper plate, to sustain the vertical pressure required.

An opening is-provided through the centre of the pivot-hub, (1', throughwhich passes the king-bolt, F, and is secured beneath the axle in theusual manner.

G represents an arm, extending radially from the Y centre of the plateor bar E to the rear, and projecting from four to six inches beyond thecircle, to the upper side of which the pole or reach is attached, whileto itslower side is secured one end of a brace, H, which passes beneaththe axle and is attached to lug, g, projecting forward from the upperplate E. The brace H has a sufiicient width "beneath the axle to allowof an opening, through which the lower end of the king-bolt passes.

It will be seen that this construction of the circleiron possesses manyadvantages over any in use, as

by it .the king-bolt is relieved from all lateral strain and wear,- anda joint is furnished which is very durable and strong.

It also provides a convenient means for connecting the pole or reachwith the'circle-iron, and throughit, with the forward axle, and, as theparts of the device are few, and with exception of the king-bolt, can beconstructed-of malleable iron, it can be furnished at a smallercost-than any new in use.

Having thus fully set forth the nature and merits of my invention, l 7

What I claim, and desire to secure by Letters Patent, is v Thewithin-described fifth-wheeler circle-iron, when constructed asdescribed, with the axial pivot-hub d and corresponding recessed boss7), and with the radial arm G, substantially as and for the purposespecified.

In testimony that I claim the foregoing, I have hereuntoset my hand,this 29th day of March, 1869.

DANIEL WEAVER.
